Why shouldn't civil aircraft be equipped with escape facilities?
Everyone sucked out. Besides, a group of people carrying their umbrellas, who do you think will be the first to jump? Jump may not be safe landing.
The common escape facilities for civil aviation are the life jackets and rafts for aircraft landing passengers, and the aircraft's own escape slides, and then the oxygen masks.
Ha ha, have also can not use ah. Civil aircraft are pressurized cabin, the air pressure on the opening door
